Combo Lit Channel Letters

Combo lit channel letters, or combination lit channel letters, are channel letters that have both front and rear illumination. The letter’s front is illuminated with LEDs, while the rear has a halo effect. This results in a vibrant and eye-catching sign that will pique the interest of people walking by. Combo illuminated channel letters are an excellent solution for businesses seeking to create a huge impression with their signage.

Front Lit Channel Letters

Front-lit channel letters are the most popular form of channel letter. They are illuminated from the front, with light shining through the letter’s face. Front illuminated channel letters are usually made of metal and come in various colors and typefaces. They are an excellent alternative for businesses looking for a clean and professional image in their signage.

Back Lit Channel Letters

Backlit channel letters, also known as reverse-lighted channel letters, are illuminated from the rear. The light shines through the rear of the letter, giving it a halo aspect. Backlit channel letters are an excellent alternative for businesses looking for a more subtle and elegant appearance in their signage. They are frequently utilized in high-end retail outlets, restaurants, and hotels.

Open Face Channel Letters

Letters without faces are known as open-face channel letters. The letters are open, enabling light to shine through. Open-face channel letters are an excellent solution for businesses looking for a one-of-a-kind and visually appealing sign. They are commonly utilized in pubs, nightclubs, and other types of entertainment establishments.

Raceway Mounted Channel Letters

Channel letters affixed on a raceway are known as raceway-mounted channel letters. A raceway is a mounting structure commonly constructed of aluminum. The raceway is attached to the structure, as are the channel letters. Raceway-mounted channel letters are an excellent solution for businesses looking for a clean and professional design in their signage. They are commonly utilized for commercial structures like retail malls and office buildings.
